Hi,
I'm checking out the Ground meterial in KeyShot 4 to catch shadows and reflections on
floor and wall planes simultaneously. I was hoping this would blend my rendered objects much better into a backplate image, but my attempts are not very successful so far...

I am attempting to integrate a radiator into an interior backplate. I have aligned the radiator to 2 perpendicular planes that serve as the floor and wall. I have applied the new Ground material to both planes. (ref. images:
TEST_rad-in-interior_floor&wall-planes_01 &
TEST_rad-in-interior_floor&wall-planes_02)
My issues fall in two main categories:A. Using environment lighting:* When I make only the floor plane visible, my image looks OK. (ref. image:
TEST_rad-in-interior_EV-lighting_01_floor-visible)
* When I make only the wall plane visible, my image looks OK too. (ref. image:
TEST_rad-in-interior_EV-lighting_02_wall-visible)
* When I make
both the floor and wall plane visible...my image looks
not quite OK. Something strange is going on, due to interaction between floor and wall planes. (ref. image:
TEST_rad-in-interior_EV-lighting_03_floor&wall-visible)
B. Using (planar) area lights: (ref. image:
TEST_rad-in-interior_area-lights)
(More of a rant actually...
)* The
floor and wall planes are completely blown out by the area lights. (ref. image:
TEST_rad-in-interior_area-lights_01_floor&wall-visible)
The influence of area light brightness on the Ground material is undesirable in this scenario.
I hope someone can help me out!

greetings,
Dries
